--- Quote ---How does the the tip set and control the temperature? --- End quote --- The old Weller TCP irons controlled temperature with ferro magnetism. When the tip temperature is below the magnetic curie point, the tip stays magnetised. The magnetism would pull a switch in the shaft closed, turning on the heat. When the tip goes over the temperature threshold for the magnetic curie point, the magnetism is lost, opening the switch and hence stops heating. The system self regulates the tip temperature. You can change the tip temperature by changing the tip to one with a different magnetic curie point. I know 2 temps are available 6 and 7 tips. I beleive that refers to the temp in °F Ie in the 600°F range and in the 700°F range. There may be a 3rd temp available but I have never seen one. |

Considering a Soldering Station soon and I don't know how useful an adjutable temp control will really be. I know I definitely don't want one of those digital ones. |

The Weller TCP irons are pretty much bullet proof. Mine's 45 years old and has yet to fail me. --- Quote ---I know 2 temps are available 6 and 7 tips. I beleive that refers to the temp in °F Ie in the 600°F range and in the 700°F range. --- End quote --- #8 for 800F tips exist also. |

I found a Weller TC202 at a yard sale for $10. Any good source for authentic/non-foreign tips or accessories? |

AFAIK, Weller doesn't suffer from knockoffs. The Chinese cloners don't are about Weller. They settled their hooks on Hakko. The rumor is that Weller tips used to last forever and now they don't. Whether it's because "made in Mexico" and "genuine Weller" are now synonymous, or whether they changed something intentionally, who knows? But I have read that this change coincided with moving their tip manufacturing south of the equator. I think they might still make some of their tips in Europe, but how you can buy one or the other, who knows. They are all authentic. Firsthand, I have experience only with the new Wx stations. The station is not reliable, longterm. 25% units dead thru 6 years. And the expensive $30.00 to $45.00 micropencil tips wear out way too fast. |
